TRACTION-WHEEL.

FsF'ECIF-IGATION forming part of Letters'PatentNo. 747,764, dated December 22, 1903.

Application filed 1,..11'28, 1903.

To all whom it may concern.-

Beit known that LWILLIAM A. PRIOE,a citizen of the United States, residing at Peakesville, in the county of Clark and State of Missouri, have invented certain new and useful Improvements in Traction-Wheels, of which the following is a specification.

My invention relates to traction engine drive-wheels, and my object is to produce a drivewheel cleat whichwill prevent lateral slippage and eliminate the jar incident to the travel of an ordinary traction-engine on hard roads, bridges, &c.

A further object is to produce a cleat which is practically self-cleaningthat is to say, on which .sand, mud, or snow will not accumulate and stick to an appreciable extent.

Astill further object is to produce a cleat possessing the advantages above enumerated as desirable, and which is-of simple, strong, durable, cheap, and comparatively light con- 'struction.

To these ends the invention consists in certain novel and peculiar features of construction and combinations of parts, as hereinafter described and claimed, and in orderthat it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1 is a top plan view of a tractionwheel equipped with a sufficient number of my improved cleats to show their relative p0 sition and arrangement. Fig. 2 is a side view of a portion of a wheel equipped'with said cleats. Fig. 3 is a section on the line III III of Fig. 1. Fig. 4 is a section on the line IV' IV of Fig. 1. Fig. 5 is an enlarged detail perspective view of one of the cleats.

In the said drawings, 1 designates a wheel of the usual or any preferred construction, except the cleats. I

2 designates the cleats, which in plan view are parallelogram in form and preferably have their long sides at a slight angle to their ends in order that the latter maylie in the planes of the opposite edges of the wheel, while thelong sides extend obliquely of such planes, as shown in Fig. l, and parallel with the "long sides are longitudinal series of holes 3 for the rivet-s or bolts 4, by which the cleats are secured to the wheel. Each cleat is formed at its outer side with a rib 5, extending from one Serial No. 154,665.' (No model.)

end to the other and preferably at an angle to the longsides and terminating at its opposite ends in laterally-projecting flanges or lugs 6, projecting toward and terminating at the adjacent corner of the cleat, so that said end flanges or lugs shall be disposedat opposite sides of the central rib 5, and in order that the cleat shall not be unnecessarily-heavy it is formed at its inner side with a recess 7, correspond in g in cross-sectional contour to the outer side of the cleat, as shown clearly in'Fig. 3, the recess terminating short of the ends of the cleat,so as to leave end flanges 8 to prevent mud, snow, sand, &c.,entering the recess, and therefore increasing the work of the engine. As the cleats are arranged it will be seen that the oppositely-projecting flanges at the opposite ends of the proximate cleats overlap, and

thus, with the intermediate portions of ribs 5, provide abearing-surface for the full width of the wheel at all times and entirely elimimate the shock or jar incident to the travel of a wheel on which the cleats do not overlap.

It will also be noticedv that the end flanges extending in the line of travel more effectually prevent lateral slippage than where the oblique ribs alone are employed, the oblique ribs cooperating with the end flanges in this action and at the same time giving the requisite traction with the ground. It will also be noticed that by reason of the cross-sectional form of the cleat it provides no, corners in which sand, mud, or snow can accumulate and cling, and thus impede the progress of the engine.

As shown in Fig. 1,-the cleats may be 'suflicientl y wide to be arranged edge to edge upon the wheel or, if desired, may be spaced some distance apart. In the latter case, however, the spacing must be such that oppositely-projecting end flanges of proximate cleats'shall overlap in order that a continuous and even bearing-surface may be provided.-

From the above descriptionit will be apparent that I have produceda traction-wheel embodying the features of advantage enu-- merated as desirable in the statement of invention, and whileI have illustrated and described the preferred embodiment of the same it is to be understood that I reserve the right to make such changes in "the form, propor- IOO tion, detail construction, and arrangement of the parts as properly fall within the spirit and scope of the invention.

Having thus described the invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. A traction-Wheel, provided with peripheral cleats, having ribs extending obliquely of the wheel and terminating at their opposite endsin oppositely-projecting end flanges; the end flanges at one side overlapping those at the other side of the wheel.

2. A traction-wheel, provided with peripheral cleats having ribs extending diagonally of the wheel, and terminating at their opposite ends in oppositely-projecting end flanges; said eleats being formed with recesses at their inner sides and with flanges closing said recesses at their ends.

3. A traction-wheel eleat having a rib at its outer side which terminates at its opposite ends in opposiiely-projecting flanges; said cleat being approximately V shape in cross section, externally to avoid the production of corners, and internally to reduce weight, and being furthermore provided with end flanges 8.

In testimony whereof I alfix my signature in the presence of two Witnesses.
